Hi Anu
I would say that in Archi ... the photography can always come in handy, and you don't need to be a pro at it.
well the jobs you are looking for would depend on the stream that you want to be the main .... I mean if you are a pro at photography with a secondary base in architecture, I can see the jobs in archi and other landscape magazines coming your way.
if the archi is your main thing than i can see that it can be good help with the planning and all
neways I don't know much about it as I my knowledge of archi is limited from some friends at SPA Delhi long time back
